It is a fixed semi-pulley worked with diamond tools on the sliding surface of the belt and with a recalculated angle to increase the rate of change. This item completes the Multivar and makes it unstoppable. Studied for the line of scooter variators, it further improves the working conditions of the transmission belt. It is not a simple accessory, but a very important part for the duration of all the elements of the transmission. The temperature that occurs inside the casing where V-belt variators work at certain moments is prohibitive and at times certain parts, such as the transmission belt and variator rollers, suffer irreparable damage and sometimes the rollers can reach the melting point. Ventilvar, in addition to other advantages, has a higher cooling capacity than the original, a result that makes it essential for safe and sporty driving.
NB: combinable with Multivar and original variator
